P0138,P0139 both refer to the right rear oxygen sensor. repalce sensor
P0302 is a cyl #2 misfire- could be bad coil or plug or injector.
P1320- Ignition signal interruption during crank/running- possible causes are- circuit open or shorted, defective power transistor(integrated with coil), defective condensor,defective crank sensor (CKP) , or CKP circuit open or shorted

if you got an individual cyl # (p0302) to go with p1320 consider yourself one lucky person. typically when p1320 sets it comes with a p0300, random misfire, code. nissan recommends replacing all 6 ignition coils with updated ones. since yours gave you the p0302 i might be inclined to try just the coil for that cylinder. i would highly suggest putting new plugs in as well.
